Question

我已经使用了Enthought Canopy 1.4.1一段时间，而且我从来没有遇到过问题。今天我启动了程序，无论我做什么，控制台都没有给我任何东西或类似的东西：

IOError                                   Traceback (most recent call last)

     46         while stream.getsockopt(zmq.EVENTS) & zmq.POLLIN:

        global kernel.do_one_iteration = undefined

        global IOError = undefined
    493     
    494     def _rebuild_io_state(self):

IOError: Stream is closed

即使我做的事情很简单：

a = 1

它卡住了，它给了我以前的IOError。请帮忙，我需要它工作！

感谢，卢卡

当您说您执行完全卸载时，步骤3和4，您的意思是这个链接吗？：https://support.enthought.com/entries/23580651-Uninstalling-and-resetting-Canopy

如果是这样，你仍然得到错误，那么你可能已经创建了一个与系统库模块同名的python文件，因此干扰了python的启动。查看小时主目录，或PYTHONPATH中的每个目录（如果有）。

另外：查看您的环境（在终端中键入env）以查找可能干扰的任何与python相关的环境变量，因为您的“昨天最后一件事”安装可能会破坏您的系统。
